According to a 1998 interview found on a British site called "Boxing Monthly", Buffer originally experimented with other catch phrases, including "Man your battle stations, because we're going to war", before first using "Let's get ready to rumble" in 1983.

Now he's famous worldwide and in addition to his television and movie appearances, also has been contracted for several fighting video games.

Buffer has his own website (www.letsrumble.com) where he advertises his services and sells clothing and other items with "Let's get ready to rumble".
